Value Collection SC2160024 Countersink 3/8 in 60 Deg 6 Flute

Product Description

The VALUE COLLECTION SC2160024 is a single-end cobalt steel countersink designed for creating clean, conical recesses in metal workpieces. With a 3/8 inch head diameter and a 60-degree included angle, it produces accurate seat geometry for flat-head fasteners and similar hardware. The 6-flute configuration distributes cutting load evenly, reducing chatter and improving surface finish in harder materials. The bright, uncoated finish is standard for cobalt-grade tooling and suits a wide range of ferrous and non-ferrous applications. This countersink is installed and used by machinists, tool-and-die technicians, and skilled fabricators working with drill presses, milling machines, or hand-held power drills.

This countersink is suited for countersinking operations in metal fabrication, maintenance and repair, and production machining environments. The 1/4 inch straight cylindrical shank accepts standard drill chucks and quick-change collet systems commonly found in machine shops and field maintenance settings. It is intended for right-hand cutting direction and does not include a pilot, making it appropriate for use in pre-drilled holes where the operator guides tool alignment manually.

Key Features

• 3/8 inch head diameter with 60-degree included angle for standard flat-head fastener seating
• 6 flutes for reduced chatter and improved finish on harder materials
• Cobalt steel construction for increased heat and wear resistance compared to standard high-speed steel
• 1/4 inch straight cylindrical shank fits standard drill chucks and collets
• Right-hand cut, single-end design with no pilot included
• Bright, uncoated finish suitable for general-purpose metal countersinking

Compatibility

Designed as a general-purpose countersink for use in drill presses, milling machines, and hand-held power drills equipped with a 1/4 inch or larger chuck or collet.

Installation Notes

Installation and use should be performed by qualified machinists or trades personnel familiar with rotary cutting tools. Secure the shank firmly in the chuck or collet before operation and verify runout before cutting. Always use appropriate cutting fluid or lubricant when working with ferrous metals to extend tool life and improve finish quality. Do not exceed the recommended RPM range for the material being cut, and wear appropriate eye and face protection at all times.
